Pulse wave parameters as a predictor of the development of post-transplant diabetes mellitus after kidney transplantation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundKidney transplantation is the preferred treatment for patients with end-stage renal disease, significantly preserving kidney function and patient quality of life. However, post-transplant diabetes mellitus (PTDM) is a common complication, occurring in approximately one-third of renal transplant recipients. This study aims to evaluate the role of pulse wave parameters in predicting PTDM and to identify other pre-transplant risk factors.
methodsThis prospective cohort study included 105 patients on the kidney transplant waiting list from 2017 to 2022. Exclusion criteria included any pre-existing diabetes mellitus. Patients underwent physical examinations, laboratory analyses, and pulse wave analysis before transplantation and one year post-transplant. PTDM diagnosis followed International Consensus Guidelines. Data were analyzed using Wilcox test, Bonferroni correction, May-Whitney U-test, and Fisher's exact test, with p < 0.05 considered statistically significant.
resultsPost-transplant, 21% of patients were diagnosed with PTDM, increasing to 35% 3months post-transplant and 43% at one year post-transplant. Significant findings included: Pre-transplat risk factors for developing PTDM: Proteinuria (p = 0.037, OR = 3.942) and perioperative hyperglycemia (p = 0.003, OR = 4.219 at 3 months; p = 0.001, OR = 4.571 at 1 year). Pulse wave parameters for developing PTDM: Pre-transplant Aortic PP > 45 mmHg (AUC = 0.757) and PWV > 8.5 m/s (AUC = 0.730) were strong predictors of the development of PTDM after 3 months (p < 0.0001). Moreover, we found significant improvements in aortic pulse pressure (Aortic PP) and pulse wave velocity (PWV) post-transplant (p < 0.0001).
conclusionOur study confirms that pulse wave parameters, such as Aortic PP and PWV, are significant predictors of PTDM in kidney transplant recipients (KTR). These findings support incorporating pulse wave analysis into routine pre-transplant evaluations to identify high-risk patients. Additionally, monitoring these parameters post-transplant may aid in early intervention and prevention of PTDM, ultimately improving patient outcomes.
